Putah-Cache Arundo Eradication Project

The Putah-Cache Arundo Eradication Project is a state-led environmental restoration initiative administered by the Yolo County Resource Conservation District under the authority of the California Department of Fish and Wildlife, extended through Streambed Alteration Agreement Notification Number 1600-2019-0313-R2. The project focuses on the removal and control of invasive plant species, primarily Arundo donax and Tamarix parviflora, across approximately 96 miles of riparian areas within the Putah, Cache, Pleasant, and Westside tributary watersheds in Yolo and Solano Counties. Activities include mechanical and chemical treatments to suppress invasive vegetation, followed by revegetation with native plant species to stabilize streambanks, reduce erosion, and prevent the reestablishment of non-native weeds. The agreement’s expiration date has been extended from April 20, 2025, to April 20, 2030, providing a five-year extension to complete and monitor long-term ecological outcomes. Work is conducted in compliance with Section 1602 of the California Fish and Game Code and the California Environmental Quality Act, supported by a Mitigated Negative Declaration that confirms no significant environmental impact. The project is executed under a regulatory agreement rather than a traditional federal procurement contract, and as such, it does not include federal acquisition regulation clauses, pricing structures, payment terms, invoicing systems, or formal evaluation criteria. No contract value, cost estimates, or financial accounting data are provided, and there are no designated contracting officer representatives, key personnel requirements, or security clearances. Responsibility for oversight and final acceptance rests with the California Department of Fish and Wildlife, while the Yolo County Resource Conservation District serves as the implementing entity. Primary contacts for administrative and technical coordination are Heather Nichols of the Yolo County Resource Conservation District and Alexander Funk of CDFW. The performance location spans multiple creeks and sloughs in Northern California, with all work occurring in situ, and no delivery or packaging specifications apply since the project involves ecological services rather than goods. No formal proposal submission process, deadlines, or documentation requirements are outlined, indicating that the activity is governed by permit compliance rather than competitive procurement.
